The interlayers (2A,2B) to be used are ones made of a modified ethylene-vinyl acetate copolymer whose temperature-viscosity curve has a slope of -0.0097 to -0.01188 DEG C<-1> in a temperature range of 90 to 130 DEG C as plotted with common logarithm of viscosity as ordinate and temperature as abscissa.
Description
Technical field
The invention relates to the manufacture method of laminated glass.Particularly about making the light modulation film between two layers of sheet glass, the best that forms the dimming glass of an integral body is made the method for laminated glass.
Background technology
Dimming glass is will be by the light modulation film that constitutes of light control materials such as polyethylene film holding liquid crystal (for example, NHTechno (strain) system UMU (registered trademark) film) of band nesa coating between two layers of sheet glass, and makes it form the glass of an integral body.
Past, the manufacturing of this dimming glass, it is the polyvinylbutyral as intermediate coat (PVB) film that between two layers of sheet glass, is configured to bonding light modulation film two sides, and carry out lamination, again this layered product is placed vacuum bag, under about 100 ℃, give heating, re-use autoclave and add hot pressing (hot pressing condition, for example, 7kg/cm
2, 105 ℃).
On the other hand, in general laminated glass such as decorating laminated glass are made, someone proposes, except do the intermediate coat of bonding usefulness, also use not need the sex change ethylene vinyl acetate (sex change EVA) of autoclave treated non-plastic type with PVB is intermediate coat, in the special fair 2-11541 communique, proposition is made intermediate coat with sex change EVA etc., this intermediate coat is clamped between two layers of sheet glass, packs in the vacuum bag with this state, dipping adds the manufacture method of thermosetting laminated glass in warm water.And open in the flat 5-286742 communique the spy, propose to make in the laminated glass using sex change EVA to make intermediate coat, be configured in liner in the vacuum bag by improvement, to eliminate the method for laminated glass distortion.
Past, the PVB intermediate coat that in dimming glass is made, uses.Handle owing to must carry out autoclave, increase so shortcoming is a cost of equipment.And owing to contain softening agent among the PVB, this softening agent immerses in the light modulation layer of dimming glass; make the inner deterioration of light modulation layer,, immerse for preventing softening agent because of there being this danger; four peripheries that must use protection to exchange optical thin film with sideband carry out encapsulation process, though necessary and be not suitable for.
To this, be intermediate coat if in general laminated glass, use sex change EVA, do not carry out autoclave and handle, or plasticizer-containing not, just can not produce the problem that softening agent causes yet.Yet using sex change EVA is intermediate coat, has following shortcoming.
That is, sex change EVA is that intermediate coat is compared with PVB, wants hard under general normal temperature environment, has in addition in the temperature province of normal temperature to 100 ℃, rises sharply the descend characteristic of (that is, viscosity/temperature curve very tilts) of viscosity with temperature.Therefore, when the pressurization in bonding process heats up, as have temperature deviation, in the low part of temperature, intermediate coat becomes harder than other parts, is easy to produce local stress in this part.On the one hand, the light modulation film is very weak to the local stress from the outside, and when particularly gripping object was liquid crystal, the little by little deviation that stress causes will cause the noticeable change of optical characteristics.For example, when using UMU thin film fabrication dimming glass, EVA makes intermediate coat with sex change, when adding heat bonding in common thermal source vacuum furnace, obviously there is the obscurity spot shape of said dimming glass in temperature distribution, and the result causes outward appearance unusual (partially transparentization).
Because this situation, the past as the intermediate coat of dimming glass, is intermediate coat without sex change EVA, and must use autoclave.As the countermeasure of softening agent, must use PVB to exchange the optical thin film periphery and seal.
Disclosure of an invention
The present invention its objective is the manufacture method that a kind of high quality laminated glass is provided for solving above-mentioned old problem, and the sex change EVA that is to use not autoclave processing can not have problems because of softening agent is an intermediate coat, does not produce local stress, can carry out evenly bonding.
The manufacture method of laminated glass of the present invention, it is characterized in that passing through resin film between several layers of sheet glass, and be bonded in the method for manufacturing laminated glass of an integral body, between above-mentioned sheet glass and resin film, make above-mentioned sheet glass and resin film laminated intermediate coat.Again this laminate is flooded in liquid, make the method for laminated glass by heating, as above-mentioned intermediate coat, use temperature (℃) be transverse axis (X-axis), the denary logarithm of viscosity (poise) ρ is that the obliquity of the temperature/viscosity line of the longitudinal axis (Y-axis) is-0.0097～-0.01188 ℃ in 90～130 ℃ scope
-1The sex change ethylene vinyl acetate be intermediate coat.
Among the present invention, because using the obliquity of said temperature/viscosity line is intermediate coat than the lower sex change EVA of past specified range, promptly, use is an intermediate coat to the very little sex change EVA of the changes in hardness of temperature, simultaneously, as the heating adhesive means, adopting does not have temperature deviation to carry out dipping heating in the liquid of even heating, and local stress is controlled at the good bonding of minimum.This sex change EVA be intermediate coat preferably 5% spring rate be 5.4～8.0kg/cm
2℃.
With regard to its reason, the said temperature/viscosity line obliquity of past as the sex change EVA of the intermediate coat use of General Sandwich glass is about-0.0131 ℃
-1, 5% spring rate is about 12.7kg/cm
2℃, and, very big with respect to the changes in hardness of temperature, so the local stress of being easy to generate.
Method of the present invention is to using the light modulation thin film fabrication dimming glass a little less than the local stress effective especially.
